Meng Yi refused, and Chen Xu hit a wall again.

Returning to Zuo Xiang's Mansion in a daze, Chen Xu sat alone in the study in a daze, several maids had never seen their Hou Ye in such a depressed mood, and they all stood outside the door in fright, and they didn't dare to come out.

If you really want to investigate this matter, it shouldn't be difficult, but after finding it out, it's also a crotch, and it can't be washed clean, the reason is naturally Feng Quji and Meng Yi's worries, no one in the Wang family is offended, so if he wants to investigate, he can only do it himself, Meng Yi and Feng Quji have already stated that they will not be involved in this trouble.

But for Chen Xu, it was definitely a wrong decision to personally arrange someone to investigate, because he was in charge of Zhongshu Province, neither the Ministry of Supervision nor the Ministry of Criminal Affairs, and he had no right to investigate at all.

It's a pity that the two powerful and capable people he chose didn't accept it.

But in Chen Xu's opinion, if this matter is not handled well, it may really cause a big disaster.

Li Mu is like a god in the minds of the people of Zhao State, if this matter is not handled well, the people of Zhao will hold a grudge, after a long time, not only will it not slowly calm down as Meng Yi and Feng Quji said, but will accumulate more hatred and anger, and finally count this breath on the emperor's head, once there are more conflicts to accumulate more hatred and contradictions, it is not impossible to rebel in the end.

And Daqin, with his continuous efforts, finally has the opportunity for rapid development that is now peaceful and peaceful, if there is turmoil again, many reforms that have just begun will be lost, and one war after another, after all, will slowly wear away the little wealth that has been accumulated with great difficulty.

Just attacking the Western Regions and Lingnan, the annual consumption of the imperial court is more than five million stones, grain and grass, and the conscription of more than 100,000 people, prisoners and slaves are more than 100,000, and now Lingnan is about to be conquered, the army cannot be quickly dismantled, but will remain for at least a few years to maintain the peace of the Lingnan lands, this consumption will be continuous, and a Xiang rebellion, and finally according to the estimation of the court, the loss is at least three million stones, the production and life of the local people have not recovered in the past two years, tens of thousands of people died in the military disaster, hundreds of thousands of people were displaced, If there is another rebellion in the north, the turmoil will be even worse, and a large army will be summoned to recruit people's servants and soldiers, grain, grass, carts and horses......

After sitting in the study for a full hour, Chen Xu depressedly put down this matter that he couldn't think of a countermeasure for the time being, and instructed the guards to prepare a carriage and horse to go to the engineering college.

The chemistry lab is filled with a rich floral scent.

Several glass stills are still distilling, and a group of alchemists are working back and forth processing flower petals and collecting essential oils.

More than half of the more than ten baskets of petals have been used, and the rest are osmanthus and chrysanthemums, and the petals have wilted very much, but it seems that there is no big problem in distilling essential oils, because essential oils continue to drip from several distillation equipment.

"Master Hou, this is the essential oil collected yesterday and today, a total of five bottles of ......"

Seeing Chen Xu come in, the manager of the laboratory, an old monk with white hair and white fairy bones, hurriedly greeted him and took Chen Xu to see the fruits of the hard work of a group of people for nearly two days.

Five small crystal glass bottles, which were used to hold reagents, were filled with more or less transparent liquids of different colors, and all of them were tightly corked with corks, and there were labels on the bottles, three of which were marked as osmanthus, one was marked as chrysanthemum, and the last bottle was slightly brown as vanilla.

Vanilla actually does not refer specifically to a certain kind of flowers and plants, but a general term for fragrant wild grasses, many of which belong to herbal medicines, so they have long been used by people to make medicine sacs to repel mosquitoes, so the baskets of herbs collected by the servants of the Qinghe Hou Mansion are very messy, including common mint, orchid grass, perilla, mugwort, and even many wild flowers, wild grasses and wild fruits that Chen Xu does not know at all, but these things are mixed together, and several alchemists do not pick them up, but chop them together and put them in the distiller to refine, In the end, I got about a tael of light brown essential oil.

Chen Xu first opened the bottle of mixed flavor of vanilla essential oil and smelled it, only to feel an extremely pleasant and refreshing smell rushed into his heart, this smell with the coolness of mint, the lightness of bluegrass, the lightness of perilla, and all kinds of scents of mountain flowers in the thick spring, as if he saw a field full of flowers in an instant.

"Yes, yes, this vanilla is very good!" Chen Xu hurriedly covered the vanilla essential oil in admiration, and opened the osmanthus essential oil and chrysanthemum essential oil one after another and sniffed it, feeling that there was not much difference from the fragrance of the sachet he smelled, but the taste was countless times stronger than pure, as if he had inhaled the fragrance of a whole basket of petals at once, which made people a little fascinated.

"Master Hou, you are really whimsical, you can even think of using a still to refine the fragrance in the petals, but this bottle is too little, and the water is not enough!" The old fairy-like Taoist priest stood beside Chen Xu and said with admiration on his face.

"It's not for drinking, it's for spraying on your clothes to add fragrance!" Chen Xu's explanation with black lines on his head.

"Ugh!" The old Taoist priest was stunned for a long time, and stammered: "Master Hou, why do you want to spray it on your body to add fragrance, is it to deodorize?" ”

"Do you have a mother-in-law?" Chen Xu asked rhetorically.

"Lao Er pursues the path of immortals, refining medicine for immortality, and has never married a wife!" The old Taoist priest said puzzledly.

"That's right, you don't like women, you can't explain this matter clearly, go and get the purified alcohol and distilled water, and then take the dropper and test tube, Ben Hou will use it." Chen Xu pursed his lips and stopped communicating with this old Taoist priest who pursued the way of heaven without a wife and children.

Talking to a Taoist priest who doesn't like women about women, obviously can't urinate a pot.

For most of the next day, Chen Xu stayed in the chemistry laboratory.

By the time of Shen Shi in the afternoon, a group of alchemists had refined all the remaining baskets of petals, and obtained a total of five bottles of osmanthus essential oil, three bottles of chrysanthemum essential oil, and a bottle of vanilla essential oil, each bottle was full of about one tael, so all these essential oils added up to less than nine taels, and at present, one catty of Daqin is sixteen taels, and one catty is only equivalent to half a catty in later generations, that is to say, this is full of more than ten baskets of petals, and the total amount of essential oil refined in the end is less than one hundred and fifty grams.

And it's not pure essential oils, because the bottom of these essential oils is clearly divided into two layers, and there is a part of water underneath, and if you let it stand for a while, it is estimated that more water will precipitate.

"Sure enough, it's the essence, it's too little!"

Chen Xu looked at the row of test tubes of different colors on the test tube rack and the several large bottles of perfume that had been prepared on the table.

After most of the day's work, after constantly experimenting with test tubes, Chen Xu still concocted a few bottles of perfume that he felt could be used with his own feelings.

Direct spraying of essential oils can naturally be, but it is too wasteful, and the essential oil volatilizes very quickly, the fragrance is too strong, in fact, it is easy to cause discomfort to some people, and after mixing essential oil with alcohol into perfume, the fragrance is light at the same time, it is also easy to attach to the surface of clothes and skin, forming a long-term light fragrance, only to have red sleeves to add fragrance, dark fragrance sleeves of the kind of quiet and elegant that Chinese like.

A few bottles of perfume were concocted, and there were still some essential oils left, and Chen Xu asked the laboratory manager to put them away.

"Master Hou, do you still want the perfume in this test tube?" A few Fang Shi came up with a ghostly head.

"What? A group of rough men who don't want to marry a wife and have a baby, do you also want to go to the garden to seduce the little lady? Chen Xu said with a smile.

"Hehe, it's not interesting to do experiments in the garden, it's just ...... It's just ......" a middle-aged Fang Shi shrank his head and stopped talking.

"It's just that it doesn't matter what you say, if what you say is reasonable, Ben Hou will give you these perfumes!" Chen Xu waved his hand.

"Master Hou, we have joined the chemistry laboratory for more than half a year, the chemical experiment is indeed mysterious and interesting, but we have almost nothing to study for half a year, and talk about tea with a group of colleagues on weekdays, I always feel faceless, this essential oil and perfume are also the first useful things we make with you, although it is a woman's thing, but it can also fill face, take it out and show it with many friends, let them see our research results......" A man in his thirties with black beard and black hair plucked up the courage to speak out.

Chen Xu couldn't help but nod after hearing this, "Yes, you do have to come up with some scientific research results for those people to see, chemical experiments are not a study that will only make some bottles and cans all day long, but will also come up with things that the world can't imagine at all, this process of refining essential oils to make perfumes is a very classic chemical process, which can be used to process a variety of different items, at the moment it is to refine the essential oil of flowers, and then you can also study and refine the essence of medicinal materials, which can be used to make more effective and convenient preparations for drinking...... ”

"Hey, Master Hou's words are reasonable, this distillation preparation is similar to the one we used to boil potion to refine the elixir, all of which are to get out the essence of the medicine!" A group of alchemists instantly looked surprised as if they had discovered a new continent.

"Well, you can carry out research on this matter on weekdays, such as refining common drugs into potions or making granules with other items, etc., you are all proficient in pharmacology, it should not be difficult to understand, the difficult thing is how to take its essence to remove its dross, and get the really useful ingredients in the medicine, this matter is very important but also very complicated, so you can experiment slowly, three years, five years or even eight years and ten years, as long as you can succeed, in the future, your name will inevitably be left on the history books of China for thousands of yearsAs the pioneers of this new type of medicine, you will also become a famous medical Taoist who will be remembered and inherited by future generations, and you will be remembered for eternity......"

Chen Xu said a few words, and suddenly the irritated eyes of a group of alchemists glowed red, and they all blushed and began to pant heavily, clenching their fists like bulls in estrus and glaring at each other, Chen Xu felt that if he threw a piece of red cloth out, this group of alchemists would be able to collapse the laboratory in an instant.

"By the way, you'd better communicate with Imperial Doctor Xu in the health center about this matter, they now have several pharmaceutical factories, making all kinds of pills and powders, as long as you develop successfully, it will be a big project to make a fortune by cooperating with the pharmaceutical factory, these perfumes in the test tube are sent to you, which is considered a reward for you for these two days, by the way, the production method must not be revealed......"

Chen Xu put a few bottles of made perfume into his satchel and said.

"Don't worry, Master Hou, we will be tight-lipped!" A group of alchemists hurriedly nodded together, and then quickly distributed the perfume in several test tubes, and each of them also found a small glass reagent bottle and carefully put it away closely.
